The primary objective of a risk awareness training program is to enable risk-based decision making, which means making decisions that take into account the potential risks and opportunities associated with each option. A risk awareness training program should aim to develop a common understanding of risk across multiple functions and business units, achieve a better understanding of risk for competitive advantage, and build safeguards against earnings-related surprises1. A risk awareness training program should also cover the basics of risk management, such as the risk management process, the roles and responsibilities of different stakeholders, the risk appetite and tolerance of the organization, and the tools and techniques for identifying, analyzing, evaluating, and treating risks234. A risk awareness training program should also include practical examples and case studies to illustrate how risk management can be applied in different scenarios and contexts5.

Segmenting the application within the existing network is the most effective control to manage a legacy application that relies on software that has reached the end of extended support, as it isolates the application from the rest of the network and reduces the attack surface and the potential impact of a compromise.
Subscribing to threat intelligence, applying patches for a newer version of the application, and increasing the frequency of regular system and data backups are not the most effective controls, as they may not address the root cause of the risk, or may introduce additional costs or complexities, respectively.

An information asset inventory is a list of all the information assets that an organization owns or uses. It includes information such as the asset name, description, owner, location, classification, value, and dependencies. The primary objective of maintaining an information asset inventory is to provide input to business impact analyses (BIAs), which are used to identify the criticality and recovery priorities of information assets in the event of a disruption. By having an updated and accurate information asset inventory, an organization can ensure that the BIAs reflect the current state and needs of the business processes that rely on the information assets.

The first thing that should be done from a governance perspective to secure the information assets of a newly incorporated enterprise is to establish an inventory of information assets. An inventory of information assets is a document that lists and categorizes all the information assets that the organization owns, uses, or manages, such as data, documents, systems, applications, and devices. An inventory of information assets helps to identify and classify the information assets based on their value, sensitivity, and criticality, and to determine the appropriate level of protection and control for each asset. An inventory of information assets also helps to support the development and implementation of other information security activities, such as risk assessment, policy formulation, awareness training, and incident response. The other options are not the first thing that should be done, although they may be important steps or components of the information security governance.
Defining information retention requirements and policies, providing information security awareness training, and establishing security management processes and procedures are all activities that can help to secure the information assets, but they require the prior knowledge and understanding of the information assets.

The most important factor to the effectiveness of key performance indicators (KPIs) is relevance. KPIs are metrics that measure the achievement of the objectives or the performance of the processes. Relevance means that the KPIs are aligned with and support the strategic goals and priorities of the organization, and that they reflect the current and desired state of the outcomes or outputs. Relevance also means that the KPIs are meaningful and useful for the decision makers and stakeholders, and that they provide clear and actionable information for improvement or optimization. The other options are not as important as relevance, as they are related to the approval, review, or automation of the KPIs, not the quality or value of the KPIs.
